1 mole of any compound will contain 6.023 × 10²³ particles. That implies, 5 moles of NH3 will contain 5 × 6.023 × 10²³ NH3 molecules. So, 5 moles of NH3 will contain 3 × 5 × 6.023 × 10²³ H atoms

Answer 2

Answer:

1 mole of any compound will contain 6.023 × 10²³ particles. That implies, 5 moles of NH3 will contain 5 × 6.023 × 10²³ NH3 molecules. So, 5 moles of NH3 will contain 3 × 5 × 6.023 × 10²³ H atoms
